Download or read book Viking DNA written by Stephen Harding and published by Nottingham University Press. This book was released on 2011-02-01 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on men from old families in England’s Wirral and West Lancashire regions, this survey traces the DNA of the local populace back to their Viking ancestors in order to determine the impact of past societies on their genetic make-up. Arguing that the areas exhibit many archaeological and historical features proving them to have had a clear Viking presence, this account provides background information on Viking settlements as well as conclusions drawn from the DNA testing. An illustrated example of how DNA methods can be used to learn about the past is also included.

Download or read book Viking Archaeology in Iceland written by Davide Zori and published by Brepols Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Viking North Atlantic differs significantly from the popular image of violent raids and destruction characterizing the Viking Age in Northern Europe. In Iceland, Scandinavian seafarers discovered and settled a large uninhabited island. In order to survive and succeed, they adapted lifestyles and social strategies to a new environment. The result was a new society, the Icelandic Free State. This volume examines the Viking Age in Iceland through the discoveries and excavations of the Mosfell Archaeological Project (MAP) in Iceland's Mosfell Valley. Directed by Professor Jesse Byock, with Field Director Davide Zori, MAP brings together scholars and researchers from Iceland, Britain, Canada, Denmark, Norway, Sweden, Germany, and the United States. The Project incorporates the disciplines of archaeology, history, saga studies, osteology, zoology, paleobotany, genetics, isotope studies, place names studies, environmental science, and historical architecture. The decade-long research of MAP has led to the discovery of an exceptionally well-preserved Viking chieftain's farmstead, including a longhouse, pagan cremation site, a conversion-era stave church, and a Christian graveyard. The research results presented here tell the story of how the Mosfell Valley developed from a ninth-century settlement of Norse seafarers into a powerful Icelandic chieftaincy of the Viking Age.

Download or read book Mars written by Barry DiGregorio and published by Frog Limited. This book was released on 1997 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Claims of Martian life continue to spur scientific debate; this partisan account summarizes the arguments to date. When several experiments conducted by the 1976 Viking Mars Landers returned positive results regarding signs of life, NASA scientists dismissed them as false positives. According to DiGregorio, this was based on nothing more than a refusal to accept the possibility of life beyond Earth. To bolster this argument, he surveys the history of the idea that life might exist on other planets, invoking such names as Giordano Bruno and Galileo. As our understanding of both biology and astronomy grew, the notion that life is not unique to Earth took hold in the minds of many scientists. The recent rise of the new science of exobiology opened doors to an understanding of how life might have arisen on any planet with the right conditions. Dr. Levin and Dr. Straat, who designed and built one of the Viking experiments, contribute two chapters summarizing the current status of this fascinating debate. The author's detailed research, as well as extensive interviews with Dr. Levin and others, highlights the intriguing evidence pointing to life on the Red Planet.

Download or read book Mars Direct written by Robert Zubrin and published by Penguin. This book was released on 2013-02-12 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Bob Zubrin really, nearly alone, changed our thinking on this issue.” —Carl Sagan, The Denver Post If you ever daydream about space travel and human space flight—or hope to one day rove the Red Planet alongside Curiosity—then MARS DIRECT will teach you how we can get there The human race is at a crossroads. In the coming decades, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species—or the closed, dystopian, and ultimately self-destructive world of Soylent Green, constantly at war with one another over humanity’s “limited” resources. If we plan to survive ourselves and one day travel to the stars, the human race’s next stepping-stone must be a manned mission to and the eventual colonization of Mars. In this four-part e-special, Mars Society founder Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin’s relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier and transform from a planetary society into an interplanetary society. Our future as a species requires us to take baby steps away from the cradle that is planet Earth or, ultimately, perish here.

Download or read book Children of Ash and Elm written by Neil Price and published by Basic Books. This book was released on 2020-08-25 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive history of the Vikings -- from arts and culture to politics and cosmology -- by a distinguished archaeologist with decades of expertise The Viking Age -- from 750 to 1050 -- saw an unprecedented expansion of the Scandinavian peoples into the wider world. As traders and raiders, explorers and colonists, they ranged from eastern North America to the Asian steppe. But for centuries, the Vikings have been seen through the eyes of others, distorted to suit the tastes of medieval clerics and Elizabethan playwrights, Victorian imperialists, Nazis, and more. None of these appropriations capture the real Vikings, or the richness and sophistication of their culture. Based on the latest archaeological and textual evidence, Children of Ash and Elm tells the story of the Vikings on their own terms: their politics, their cosmology and religion, their material world. Known today for a stereotype of maritime violence, the Vikings exported new ideas, technologies, beliefs, and practices to the lands they discovered and the peoples they encountered, and in the process were themselves changed. From Eirík Bloodaxe, who fought his way to a kingdom, to Gudrid Thorbjarnardóttir, the most traveled woman in the world, Children of Ash and Elm is the definitive history of the Vikings and their time.

Download or read book From Habitability to Life on Mars written by Nathalie A. Cabrol and published by Elsevier. This book was released on 2018-06-29 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. - Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission - Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) - Includes contributions from authors directly involved in past, current and upcoming Mars missions - Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation
